Abstract

The DNS-Based Authentication of Named Entities (DANE) specification [RFC6698] introduces the DNS "TLSA" resource record (RR) type ("TLSA" is not an acronym). TLSA records associate a certificate or a public key of an end-entity or a trusted issuing authority with the corresponding Transport Layer Security (TLS) [RFC5246] or Datagram Transport Layer Security (DTLS) [RFC6347] transport endpoint. DANE relies on the DNS Security Extensions (DNSSEC) [RFC4033]. DANE TLSA records validated by DNSSEC can be used to augment or replace the use of trusted public Certification Authorities (CAs).
